This article may be helpful for the following reasons:
These are the list of items we recommend checking/setting in the web interface of the EMH given the above scenarios.
Example:
- Wanting to share devices and datapoints on the Device List of the EMH via BACnet/IP
- Having difficulty seeing/detecting the instance ID#s and subsequent objects from the EMH
These are the list of items we recommend checking/setting in the web interface of the EMH given the above scenarios.
- BACnet > Gateway
- Meters shared via BACnet is set to All
- All items below are showing green check mark status
- Check BACnet base ID# setting on that page, and note this number (this is the base object instance number)
- BACnet > Setup
- Confirm BACnet port matches that of the other devices
- Adjust virtual network number if needed
- Set BBMD mode and distribution accordingly; typically needed when IP of EMH is not on the same subnet as the BACnet system
- BACnet > Discover
- Scan Device ID# between the base object instance number and the base+250 . Devices on the Devices > Device List should appear on the screen, indicating what BACnet instance numbers they are located on.
- On any of those line items, click the "objects" link for object datapoint listing with the associated analog input #’s. These can be listed as a BACnet EPICS template if desired by clicking the appropriate button.
- Scan Device ID# between the base object instance number and the base+250 . Devices on the Devices > Device List should appear on the screen, indicating what BACnet instance numbers they are located on.
Example:
 EMH connected devices list |
 Example of live readings from device 5, electrical meter |
 BACnet configuration where base object ID# located under BACnet > Gateway (246000) |
 BACnet object ID#s of each device from the device list |
 Example EPICS statement showing the points list for BACnet object #246005 |
